Patented May 20,1919.

Application filed December 18., 1917, Serial NO. 207,760. RenewedOctober. 9, 1918. Serial No. 257,537.

To all whom it may concern: Be it known that I, JEssE A.-B. SMrrrI, acitizen of the- United States, residing in Stamford, in the county ofFairfield and.

State of Connecticut, have invented .certain new and useful Improvementsin Type- Writing Machines, of which the following is a specification. v

This invention relates to the class of typewriting machine illustratedin the Wernery and Smith patent, No. 1,132,055, dated March 16,1915, inwhich a fan-fold web 1s led around a cylindrical platen to be writtenupon, and in which the platen may be displaced'to permit the web to bestraightened out, so that the carbon sheets, whlch are used tointerleave the plies of the web, may

be drawn backwardly relatively to the web for receiving the ink-ribbontype impressions; while the remaining plies maybe of thin aper, andsimply or cheaply printed, suita' sending to branch ofiices.

The difficulty superposed plies through a round platen typewritingmachine is that the outer ply creeps ahead of the inner ply, owing tothe necessity of the loosely-assembled webs feeding at the same timearound thecylindrica-l platen. This creeping. is excessive where severalplies, with their interleaved carbons, are fed through the machine; the,result be ing' that eventually the outer ply is entirely out of registerwith the inner ply, so that the lines of typing, if correctly placedupon the outer ply, fall in incorrect positions upon the inner plies,especially the innermost.

According to the present improvements,

newed after-the completionof'the writin of each of the successive -forrns thereon, so t at le to retain for office copies or for I found inrunning separate provements applied thereto.

the platen, is carried a registration renewing I .or re-alining device,comprising a set of pins or gages to enter said perforations in the web,and thereby slip the webs slightly one upon another, or cam or jog theminto proper relative register. This may be conveniently done after thelaten has been displaced or shifted upwar ly to straighten out the webspreparatory to drawing backthe carbons between the webs; and aftereffect lug-the desired registration by means of these plns, they may beused to draw forwardly the webs, to gage them preparatory to typing thefirst line of the next form or page thereon.

When the work has thus been drawn. for

wardly and gaged b using the re-alining pins the platen may be depressedto normal position, and the form or section of the work which has beenalready typed may be out OE, and the severed section may belifted ofi'figrftzie pins and removed from the mac ne; and the typing may-thenproceed upon the next form or section, which remalns, of course,accurately gaged with reference to the printing point of the typewritingmachine.

Other features and advantages will'hereinafter appear. 1

In the accompanying drawings,

' Figure 1 is a perspective view of an Underwood front-strike fan-foldtypewriting machine, generally as shown in said Wernery and Smithpatent, with the present im- Fig. 2 is a fragment of one of the webs,showing the re-alining perforations, which are duplicated upon all thewebs, whereby they may be newl registered with one another and with t eprinting point of the typewriter, preparatory to typing each freshsection or form of the web. i

Fig. 3 is an enlarged perspective detail of a flap or device that may beused to press the sheets down upon the re-registering pins, l

and alsoto prevent them from falling from the pins whil'e'the webs liestraightened out with their faces downward, as at off carries the pins,showing in section a few loose webs which have become relatively dis-"located, and which are being placed upon the pins, first to bring theminto relative registration, and then to carry them to position fortearing off the written section and locating the first blank line on thesucceeding section in position to receive the type impressions.

Fig. 5 is a sectional side elevation, illustrating the platen raised topermit straightening of the webs, and also showing the carbons drawnback and the webs advanced to position for tear' ofi' one section orform and proceeding w1th the typing of the next form.

There are illustrated in the drawings superposed webs 10, 11, 12, looseor separate one from another, each web consisting of a single ply,although it is obvious that each may consists of two or more plies.These webs are interleaved by carbon sheets 13, and the assembled work(14) is led around a cylindrical platen 15. The diameter of the curvedpath in Which the outer web 12 of the work travels around the platen isgreater than that of the path pursued by the inner web 10, so that theouter ply travels faster andcreeps ahead of themner ply; one of theobjects of this invention being to prevent such creeping fromaccumulating to such an extent as to be obj ectionable.

It is for this purpose that each of the successive sections or forms 16,constituting each web, Fig. 2, is provided with perforations 17 forminga row across the web, so that the web presents these rows ofperforations at intervals. The row of perforations is preferably at thehead of its form 16; and as .a preparation fortyping the first form uponthe work, each web is impaled uponcorresponding pins 18 mounted upon thetypewriting machine. These pins may have straight bodies of sufficientdepth to accommodate a large. number of webs, whereby the latter may bebrought into exact registration with one, another. It. will beunderstood that the webs may, at any manipulation or feeding thereof,be.- come a little out of register, as indicated diagrammatically atFig. 4, and it will also be seen that the re-registering pins 18 arepointed, so as to have a camming efi'ect upon the sheets, to slip theminto register with one another as they are pressed upon the pins. Tofacilitate thiscamming action, there may be as'manp pins 18 as desired,either two or more. he greater the number of pins, the less work thereis for each one to do upon the web, and hence less liability of any pinbending, crimping or tearing the paper at the perforation.

To facilitate thisv camming operation in registering or re-registeringthe sheets, there position it prevents the inverted sheets from falling01? from the pins 18.

By means of the same pins 18, the work is then advanced or pulled alongto position to begin the first line of typing; and the location of thisfirst line may be determined by means of an adjustable gage 24, which isplaced in the path of the part that carries the pins 18, saidpart beingpreferably in the form of a slide or carrier 25, and being constructedto slide up along a supporting bar or track 26 at the delivery side ofthe platen, said gage being preferably mounted upon the same track abovesaid slide for upand-down adjustment.

Therefore it 'will be seen that the leading sections of the webs 10, 11,"12, are first brought into register -with one another by means of saidpins 18, and then, while still impaled upon the pins, are drawnforwardly thereby to exact writing position, determined by means of saidgage 24.

The operator then returns the platen, platen frame, etc., to the normalpositions, seen at Fig. 1, and throws off the flap 19, as at Figs. 1, 3and 4, and lifts the sheets from the pinsl8, the pin-carrier 25 thensliding down to the Fig. 1 position. It will be understood that nothingis to be typed upon the first form, that is, the form at the head of theweb, which is now engaged by the pins. This first form is torn off bmeans of the usual knife 27, extending a ong the platen, and is.thrownaway, its usefulness having ended after initially registering the websand bringing them to position for writing the first line upon the secondsection. The carbons 13 may be originally inserted or located at saidsecond section.

Said second section is now in position to receive the first line oftyping, since the first blank line thereon is in register with theprinting point of the typewriting machine. The typing then proceeds, andthe section which was formerl the second (now the first) is filled outine by line, whereupon the operator swings the platen 15 u to theposition at Fig. 5, in order to straig ten out the webs, and pullsforwardly the webs and (by means of the perforations)" impales them allupon the pins 18. The latter are then in their rearmost positions, ornearest to the platen. The operator, by means of the usual handle'28,then throws back the carriage 29, which carriesthe carbon sheets 13, tothe proper station for co-acting with the next unwritten portion or form163st the work. Then' the operator pulls fo'rwardly, or away from theplaten 15, the slide 25, which carries the pins, and thereby pullsforwardly'all the webs as far as possible. The extent of this advance ofthe webs is determined (as before) by the gage 24, which is set at anydesired point upon said track or bar 26, to be engaged by an abuttingatthe' succeeding set of holes 17, throws back .40 lines of perforations32 may be provided adthe carbon carriage 29, pulls forwardly the web s,restores the platen to its depressed positiin, 'tears ofl the form justtyped, and

prqceed's' with the writing of the succeeding .form upon the web. Theleading portion of the webs may be guided by means of'adjustableside-guides 50 placed upon the table 31, which usually. Inc

nes upwardly and rearwardly from the delivery side of the platen 15.

It will, be understood that the webs may be supplied'from separatespools or rolls, or'

' relative read ustment between the webs and otherwise. l

One or more of the perforations 17 may all be used for binding thesections in loose-leaf binders. The strip orportion ofthe outer jacentto said holes upon said outer web for this purpose. I
